SAFETY BUNK AND STAKE FOR LOGGING-CARS.

Specification of Letters Patent.

Patented July 4, 1916.

7 Application filed October 19, 1914. Serial No. 867,375.

To all whom it may concern:

Be it known that I, CLAYTON T. EAID, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Safety Bunks and Stakes for Logging-Cars, of which the following is a specification.

My invention relates to devices for holding saw logs on railroad cars or the like, and has for its object the production of improve ments in the art to which belong patents issued to me as follows: 1050929, issued January 21, 1913; 1055150, issued March 4, 1913; 1071609, issued August 26, 1913; 1112690, issued October 19, 1914:.

By my present invention I am enabled to produce a reliable bunk, that is simple and durable in construction, economical to manufacture, convenient and safe to operate, and one which is not easily damaged or put out of order by accidentor negligence.

What constitutes my invention will be hereinafter specified in detail and succinctly set forth in the appended claims.

In the accompanying drawings which constitute a part of the specification, Figure 1 is a perspective view of the present preferred form of embodiment of my invention. Fig. 2 is a side elevation of a portion of the subject matter of Fig. 1 on an enlarged scale, showing in dotted lines the position of the chock block with its stake after its release. Fig. 3 is an end elevation of the subject matter of Fig. 1, showing in dotted lines the position of the operating handle after its operation to release the chock block.

Referring to the numerals on the drawings, 1 indicates a beam which, in the preferred form of embodiment of my invention illustrated, comprises a base 2, and a web 1 preferably provided with a head 3, the term web being used to denote a projecting wall extending lengthwise of the base.

As shown the beam consists of a section of a rail such as is in ordinary use on railroads. Each beam preferably carries a pair of chock blocks 4, which, when of the crutch block form, preferred,'respectively straddle the web 1 upon which they ride and to which they are adjustably secured.

As a means for adjustably securing the chock blocks to their beam, I prefer to provide each block with legs 5 and 6 which effect the straddling of the Web above referred to, and in addition thereto, to provide means of secure but sliding engagement between each block and its beam.

The head 3 with which the web is preferably provided as specified, affords in connection with lugs 8 and 9 and a cross piece 7 upon each chock block preferred means of sliding engagement, the head being essen tially a longitudinally disposed projection on the beam.

The cross piece 7 rides upon the beam while the lugs 9 and 8 upon the legs 5 and 6 respectively, extending under the projection upon the web 1 which constitutes the head 3, slidably secure the chock block to the beam.

Provision being thus made for slidably securing the blocks to the beam, it remains to make provision for securing them at desired points of adjustment which may be accomplished by any suitable block lock.

By the term block lock I designate any suitable mechanism for securing a block in any position upon its beam to which it may have been adjusted. Such mechanism should preferably be adapted for operation from the end of the beam opposite to that which carries the block which it controls; and I therefore prefer to employ for the purpose a rod 11 provided with a chockblock-engaging-member or elongated wing 14:, that is preferably corrugated, notched or toothed as illustrated in order through rotative movement of the rod to engage and disengage a projection 10 extending from each chock block.

In practice it being customary to provide each beam with two blocks, I prefer, for that reason, to provide two rods 11 for each beam secured, respectively, to opposite sides of a web 1 as by clips 12.

Each rod 11 is preferably provided with two handles for operating'it, to-wit,- a handle proper 13, by which a chock block is discharged by its block lock in the unloading operation, and an auxiliary handle 15 by which the rod 11 may be operated only when not under load to release its block for the purposes of adjustment.

The comparative lengths of the handles 13 and 15 are preferably adapted and limited to their respective offices.

To afford protection against accidental operation of each rod 11, I prefer to provide for each handle 13 an automatic safety guard which may consist of a link 16 plvoted to the beam as by an eye bolt 17. The link is so disposed as to fall by gravity over the bend of the handle 18 and to hold the latter against operative movement until after it is lifted to free the handle.

Each member 14 may be provided with av plurality of teeth to adapt it to adjustment of its chock block to different positions, but if no adjustment is required a single tooth or projection on the rod 11 will suffice to hold the chock block in place.

An important and novel feature of my present invention consists in means for combining the advantages of a bunk with those of a stake, the distinction of the two devices being well understood in the art. To that end I provide a stake 18 for each chock block adapted whenever required to be united to its block, without interference with the discharge of the block look from which upon such discharge it is free to drop away. To this end, I prefer to provide each chock block a with a cross piece 21 in addition to its cross piece 7, and to provide for engagement therewith a stake having notches 19 and 20. The notch 19 is adapted to engage the cross piece 7 and the notch 20 the cross piece 21 with hook-like effect as shown in Fig. 2. By this means the stakes serve through outward pressure of a load upon them to hold the load, but readily drop away from the chock block when the block is discharged.

The following is a brief description of the operation of my device. The beams being by any suitable means secured, usually in pairs, upon the floor of a railroad flatcar, for example, the chock blocks may be adjusted preparatory to loading. To this end it is convenient to turn the rods 11 as by aid of their respective handles 15 which are preferably provided, for the purpose of such adjustment. Each rod is rotated a suiiicient distance as required to disengage its member 14 from the projection 10 of its respective block. Thereupon the liberated block may be by hand slid along the beam to desired adjustment, as, for example, in contact with the leg next adjacent to it upon the beams, and is there secured by reverse rotation of the rod 11 and the dropping into place over its handle 13 of the proper link 16. Upon the required adjustment and locking of all the blocks of the car, the load thereof is safely secured in place ready for transportation.

To release the load the car is preferably canted toward one side. The operator goes to the higher side of the car and there, with entire safety to himself, successively lifts the several links 16 and upon rotation of the several rods 11 by their respective handles 13 thereby turning their respective wings 14 toward the web 1, discharges the lowermost blocks a from engagement with their respective rods 11, with the effect of allowing the logs to descend along the inclined beams and to drop over the ends thereof.

In the operation last described each block is prevented from falling entirely away from its beam, as by engagement between its lugs 9 and clips 12,- as shown in Fig. 2.

\Vhat I claim, within the art described, is:

1. A bunk comprising a beam, and a chock block slidably secured thereto, in combination with a rotatable rod provided with a member adapted in its movement to directly engage and to disengage said block substantially for the purpose set forth.
